I'm interested in knowing :
What is the life time of GFP in a cell ?
After division, does each "daughter" cell express GFP like the "mother" ? Meaning is there any loss in the expression of each cell ...

When two amoeba cells form from one amoeba, does spindle fibers form? Some sources say that spindle fibers do not form while an amoeba cell is undergoing cell division. If spindle formation does not ...

Homologous somatic pairing is the physical colocation and pairing of the paternal and maternal chromosomes in a cell during growth phases of a cell. This is interesting as most taxa that we know about ...

For each stages of meiosis (i.e. Interphase, Prophase I, ...), I wanted to know the time between each stages either in percentages or minutes. However, while I could find the cell cycle for mitosis ...

Are there any tests available for the public which can tell me where am I on a Hayflick limit?
If Hayflick limit is 50 for example, the results I would like to have is this
skin cells: 20 out of 50
...

For a zygote to form, two haploid gametes undergo meiosis and fuse during fertilisation. Since two egg cells (or even two sperm cells) are both haploid, is it theoretically possible for them to make ...

It is obvious that cell division in living organisms is now synchronised almost perfectly with DNA replication and, furthermore, the line of division has to intersect exactly the space between the two ...

In biology I've learned that cells rapidly divide and can grow and split undefintely, and that certain parts of the body have to grow and evolve before growing, but I am tied up on the fact that the ...

i understand that when stem cells are used to treat injuries using induced pluripotent stem cells (IPS), they can prevent the risk of having any tissue rejection and thus, there isn't a need for use ...

When free nuclear divisions occur(for instance in endosperm formation in coconut etc)....there are many nuclei undergoing kartokinesis at a given point of time...so that means each karyokinesis will ...

So there are often articles about cloning from a small piece of tissue etc.
My question is (two actually) Is the Complete information about entire organism's structure stored (as in duplicated) all ...

If germ cells produce haploid daughter cells by meiosis and are thereby "consumed" (where there was a germ cell there are then 4 daughter cells), where do the germ cells come from? I asked my biology ...

If cells in our body keep on dividing into new cells how do they ever grow old?
The only cells to grow old would be defunct cells or those who won't divide into new cells like nerve cells.
What am I ...

It is given on wikipedia that everyday 200 billion new blood cells are produced in the bone marrow. I want to understand how this is achieved. Does one hematopoietic stem cell's single division result ...

I've seen this question about HPV and the reference therein. The link states "Human papillomavirus (HPV) is a DNA virus that presents tropism for epithelial cells, causing infections of the skin and ...

I am a student of physics of mathematics with very little knowledge of biology. Nevertheless, I am very keen on biophysics and I'm trying to learn the biological concepts that I need on the way.
I'm ...

I am not a bio major but I have heard about Telomerese shortening in each cell division which leads aging and cellular death. I also read that Hayflick limit is about the number of divisions a cell ...

The following article refers to contact inhibition of cell division in epithelial cells, specifically MDCK cells: Collective and single cell behavior in epithelial contact inhibition.
In their review ...

Colchicine is a chemical usually used to cause polyploidy mutant by inhibiting chromosome segregation. It is synthesized in the Colchicum Autumnale. But what mechanism prevent C. Autumnale from being ...

I am growing algae in a container in my roof. It gets sunlight for the whole day as there are no clouds nowadays in my area. There is no lack of nutrients as I am constantly adding water mixed with ...

I am always confused about this...so when one cell which has 23 pairs of chromosomes undergoes the two meiotic divisions it produces four cells containing 1 chromatid of every chromosome pair so when ...

We know that the nucleus of the cell is the White House of the cell and its DNA is the president and it commands to make protein. So my question when DNA only codes for protein and enzymes,after the ...

Meiosis is a type of cell division that reduces the chromosome number from 2n to n to make gametes viable for reproduction in humans. I know that during meiosis, there is independent assortment and ...

On average, how many cells divide each day in a human being?
How long does a cell wait before dividing itself ?
I have tried to look on the internet but surprisingly the answer is difficult to find.....

I'm a newbie in biology and medicine. I understand that Henrietta Lacks provided the cells that formed the HeLa cell line with which much research has been done. Henrietta Lacks died of cancer. If we ...
